The 9.3x57 or 9x57 are balistic twins to the proven .358 Win. and thats high praise...

The 9.3x62 is darn close to a balistic twin of the 375 H&H in that I can get 2400 FPS with a 320 gr. Woodleigh in the 9.3 or 2500 FPS a 300 gr. Woodleigh in my .375 H&H, based on the way I load them both. That boils down to a 20 grs. more in the 9.3 or 100 FPS more in the 375, a pretty fair trade off to equal IMO...

Take your pick..The 9.3x62 is considerably more powerful, but power only works if you have a need for it. I doubt that on this side of the ocean it would make much difference as I would not hesitate to shoot the biggest bear with a 9.3x57 or a 9x57 for that matter. In Africa I would feel some better with a 9.3x62.
